This is very serious. I just didn't anticipate creating 1.5TB of data in 
one day. Anyhow for all practical purpose our main file server hosting 
user directories is now dead. Unfortunately all that nice ZFS stuff 
(copy-on-write, check-sums, consistency check, and journaling) comes 
with the price. The price is that once the volume /zfsauton is over 80% 
full NFS performance will seriously degrade and even trying to erase 
files will not work the way people are used on less sophisticated file 
system. zfsauton is now 90% full. Anyhow I have to think a day or two 
what is the correct way to proceed.
